Welcome to my Instructables on how to build a RGB LED backlight for e.g. the back of your TV or desk. The Schematic itself is very simple since the WS2812 LED Strips are very easy to interface with e.g an Arduino Nano. Note: that you do not have to use the additional MSGEQ7 Audio Analyzer circuit if you only want the […]

Just when we think we’ve seen all possible combinations of 3D printing, microcontrollers, and pretty blinkenlights coming together to form DIY clocks, [Mukesh_Sankhla] goes and builds this geometric beauty. It’s kaleidoscopic, it’s mosaic, and it sorta resembles stained glass, but is way cheaper and easier. The crucial part of the print does two jobs — it

The pursuit of audiophile hi-fi is one upon which many superlatives and perhaps a little too much money are lavished. But it’s also a field in which the self-builder can produce their own equipment that is as good or often better than that which can be bought, so it provides plenty of interesting projects along

Ever since its foundation in 2007, Forlinx Embedded Tech. Co., Ltd. has been a major manufacturer and distributor of ARM technology-based embedded products such as Single Board Computers (SBCs), development boards, and many more to major companies all over the world such as Samsung, TI, Freescale, etc. Some of their SBCs are TI (Texas Instruments) Sitara

When one thinks of audio processing, the mind doesn’t usually leap to an 8-bit micro. Despite this, if you’re looking for some glitchy fun, it’s more than possible, as [Amanda Ghassaei] demonstrates with the Arduino Uno in this 2012 throwback project. The build is designed for vocal effects, based on the idea of granular synthesis. This

This instrument was build by Lieven Menschaert and Danny Leen using an Arduino Uno and some hardware components ( rotary encoder, potentiometer and simple iron bolts). The software running the actual audio and video is a Pure Data / GEM patch. Additionaly Echonest API was used to do the sample cutup. You can send any
theMIDInator MIDI controller has been created by Switch & Lever using an Arduino Mega with its 54 digital IO and 16 analog pins to provide a wealth of inputs enabling data to pass onto a digital audio workstation (DAW) to create the actual sound. Watch the overview video below to learn more about the project and the

In most cases first project in electronics for beginners is building simple audio amplifier. That is because it requires small number of elements and not a lot of knowledge to build one. For low power amplifiers we could use integrated circuits like TDA family. But I will show how to make amplifier using operational amplifier.

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, discriminators, and quadrature detectors can be quite an exercise. There’s another demodulation method that’s not so common, but thankfully it’s also pretty easy to understand: the pulse

Presented here is an Arduino based audio meter that uses a liquid crystal display (LCD). A VU meter or standard volume indicator (SVI) is a device that displays a representation of signal level in audio equipment. In this project, the intensity of left-channel and right-channel audio signals provided as input to Arduino UNO board is displayed as
